ICYMI: The history of the Wall Street bull and other stories you shouldn't miss

Every week, one Marketplace staff member offers their favorite stories from the past few days.

Krissy Clark’s Marketplace Morning Report piece on the BART transit story got a huge digital response because Sarah Lacy, founder of tech news site Pando Daily, which is based in San Francisco, said: “If I had more friends who were BART drivers, I would probably be very sympathetic to their cause, and if they had more friends who were building companies they would probably realize we’re not all millionaires, and we’re actually working pretty hard to build something.” Lacy said the BART strike exacerbated what she sees as a philosophical divide in the Bay Area. “People in the tech industry feel like life is a meritocracy. You work really hard, you build something and you create something, which is sort of directly opposite to unions.”

Another nice digital-radio intersection: Sabri Ben-Achour’s nice Twinkie spot had a second life in the social media world when we asked, “What food as a kid do you not eat anymore?’ -- which got a huge response on Twitter. Also, apparently peanut butter and mayo sandwiches are a thing.

Marketplace Money starts a four-week series on answering questions about money. This week: our relationship with money, including why we believe in money in the first place. Nice field interview with Adriene Hill and a few high school students figuring out how to deal with and save money. Check out the whole hour.

Ben Johnson interviewed Joselyn Martinez, whose father was shot and killed when she was 9-years-old in 1986. A decade ago, Martinez decided to start searching for who killed her father online. She looked on Myspace, scoured web listings, ran background checks, and talked to detectives. And she helped find him.
